Description
Technical Field
[0001] The utility model relates to the technical field of medical infusion bottle embryo separation, in particular to a large infusion upper embryo separation mechanism. Background Art
[0002] Infusion bottles, medical configuration, are bottles used for the liquids that are infused into the human body during patient infusion. The most common material for infusion bottles is polypropylene. Polypropylene infusion bottles have high transparency, strong corrosion resistance, and are not easy to break. The small-diameter bottle mouth is easy to close and has good sealing performance. It is suitable for heating and sterilization. It is currently the most widely used infusion bottle material. Infusion bottle preforms (bottle preforms such as Figure 11 The preforms are blown into bottle bodies (as shown). Currently, during the processing of infusion bottle preforms, there is a preform separation mechanism. This mechanism allows the preforms to reverse direction, allowing them to be taken over by the next process. The current preform separation and reversing technology uses a screw rod to push the preforms forward, transferring them to a reversing device. The reversing device consists of two sprockets, a chain, and a clamp on the chain. The clamp drives the preforms to reverse direction, but the screw rod is prone to falling off when pushing the preforms forward, preventing the preforms from being transferred from the screw rod to the clamp on the reversing device.
